Source description

Qwen 2.1 description:

New version based on Qwen 2.1 (base,25 step). Inpainting resolution has been increased to 768x768.

v1 (Klein 4b-9b) discription:

Basic inpaint workflow with nodes for cropping the input image. Instead of pushing the entire image into the VRAM, it only puts 512x512 there (or more if the mask is large). Klein 4b does this in seconds, instead of tens of seconds. On the 9b model the speed increase is also noticeable. If desired, it can be used on any other model (Qwen, ZiT).
